  • Publication number: 20190194529
    Abstract: A delivery vehicle is used in a smart proppant platform technology. The delivery vehicle includes a porous substrate and an active agent that interacts with at least one constituent in an operating environment of a target location in which the delivery vehicle is deployed. The active agent changes physical or chemical characteristics of the constituent to facilitate a beneficial effect. A non-polymeric encapsulating coating is maintained until the delivery vehicle reaches the target location, wherein the operating environment of the target location causes the encapsulating coating to dissolve and release the active agent into the operating environment of the target location to facilitate the beneficial effect. In one disclosed example, the proppant is designed to maintain the opening of a hydraulically induced fracture in a subterranean formation, while also allowing for the controlled delivery of active agents. It may be used to enhance the recovery of oils and gases.

  • Patent number: 10174288
    Abstract: The present invention relates to an induced pluripotent stem cell (iPS) model for cardiofaciocutaneous (CFC) syndrome, a method for producing the model, and uses of the iPS model in the analysis of neural development in CFC syndrome. Specifically, the CFC syndrome-derived iPS and generation and differentiation of an embryonic body were induced from the fibroblasts of a CFC syndrome patient, and the CFC syndrome-derived iPS and embryonic body were confirmed to exhibit broken embryonic body shapes and no differentiation into neurons. When a CFC syndrome-derived embryonic body was induced by treating with p-ERK and p-SMAD1 inhibitors, the embryonic body exhibited a normal embryonic body shape and effectively differentiated into neurons. Thus, the CFC syndrome patient-derived stem cell model of the invention can be effectively used in the research for neural development in cardiofaciocutaneous syndrome.
